Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an improvement of ceramic blocks for road pavement.

[Conventional technology]

Conventionally, ordinary concrete blocks or ceramic tiles have generally been used for pavement of sidewalks and roads.

[Problem that the invention attempts to solve]

Concrete blocks are easy to construct because all you have to do is spread sand on the roadbed and lay them in rows on top of it, but
The disadvantage is that the surface appearance is always uniform and does not change much, and it is easily worn out. Concrete blocks also have the disadvantage that, during storage, the surface gets dark, which is characteristic of concrete, and spoils its appearance. In this respect, ceramic tiles have the advantage of looking better and not wearing out as much as concrete blocks, but they have the disadvantage of being more expensive to construct and not being water absorbent. Therefore, the present invention aims to eliminate these drawbacks of concrete blocks and ceramic tiles and provide a block that is both good-looking and has excellent workability.

[Means to solve the problem]

The construction of the ceramic block for road pavement according to the present invention is as follows. A block surface plate 2 made of ceramic is adhered and fixed to the upper surface of a block main body 1 made of concrete with an adhesive. The ratio of the short side to the long side is 1:2, and the side wall surface on the short side is formed into a single wave shape with one continuous concave part and one convex part, and the long side is The side wall surface is formed into a multi-corrugated shape consisting of two consecutive concave portions and two convex portions alternately. A chamfered portion 4 is formed on the upper edge of the outer periphery of the block surface plate 2.
is formed. Further, on the side wall surface on the short side and the side wall surface on the long side, vertical grooves 3 whose upper ends are continuous with the chamfered portions are provided.
has been established.

[Effect]

By interlocking the double waveforms on the long side wall surfaces of adjacent blocks, the single waveforms on the short side sidewall surfaces, or the double waveforms and single waveforms, the adjacent blocks are brought into close contact with each other. It is possible to easily construct a firm pavement in which they cannot be displaced or moved carelessly. In addition, grooves are continuously formed vertically and horizontally by the chamfered portions of the upper edges of the outer peripheries of the adjacent block surface plates, allowing rainwater to be received and drained away, or the received rainwater to be soaked into the ground from the joints of the adjacent side walls. It can be mixed. Furthermore, rainwater or the like that enters the grooves due to the chamfered portions quickly flows down to the ground through the vertical grooves that are continuous with the chamfered portions.

【Example】

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1 is mainly made of concrete blocks. This block main body 1 is a rectangular body with a short side to long side ratio of 1:2, and the side wall surface on the short side is formed into a single wave shape with one continuous concave part and one convex part. Further, the side wall surface on the long side is formed into a multi-wave shape consisting of alternating concave portions and convex portions and two consecutive convex portions. 2 is a block surface plate made of ceramic. This block surface plate 2 is a rectangular plate with a short side to long side ratio of 1:2, as in the case of the block main body 1, and the side wall surface on the short side has concave portions and convex portions. The side wall surface on the long side is formed into a multi-wave shape consisting of two consecutive concave portions and two convex portions alternately. Reference numeral 4 denotes a chamfered portion provided by diagonally cutting the upper edge of the outer periphery of the block surface plate 2. Block surface plate 2 and block main body 1 having the above structure
are superimposed and fixed in such a state that their short sides and long sides match each other, and therefore their single waveforms and double waveforms match each other. More specifically, the block surface plate 2 is adhered and fixed to the upper surface of the block main body 1 with an adhesive. 3 is a longitudinal groove. There are two vertical grooves 3, one on the slope of the single waveform on the side wall surface on the short side, and one on the slope of each waveform forming the double waveform on the side wall surface on the long side. The upper end of the book is continuous with the chamfered portion 4. The blocks of the present invention pave the desired road surface by, for example, placing them next to each other on a sand layer b laid on a roadbed a. Double waveforms on the side wall surfaces, single waveforms on the short side wall surfaces, or the double waveforms and the single waveforms are interlocked to bring adjacent blocks into close contact with each other. As a result, between the adjacent blocks, grooves having a V-shaped cross section are continuously formed vertically and horizontally by the chamfered portion 3 on the upper edge of the outer periphery of the block surface plate 2, and the vertical grooves 3 are formed in the grooves. The top edge is continuous. By providing semicircular grooves 3 at predetermined positions on each side of the block as in this embodiment, the vertical grooves 3 can be formed into circular grooves by matching adjacent grooves, making drainage even more effective. It is preferable to make it a target. (See Figures 2 and 3).

[Effect of the idea]

As is clear from the above description, the ceramic block for road pavement according to the present invention provides the following effects. By interlocking the double waveforms on the long side wall surfaces of adjacent blocks, the single waveforms on the short side sidewall surfaces, or the double waveforms and single waveforms, the adjacent blocks are brought into close contact with each other. It is possible to easily construct a firm pavement in which they cannot be displaced or moved carelessly. Moreover, the ratio of the short side to the long side is 1:2, and
The side wall surface on the short side is a single waveform with one continuous concave part and one convex part, and the side wall surface on the long side is a double waveform with two consecutive concave parts and two consecutive convex parts. Therefore, in addition to joining blocks by interlocking their short sides or long sides together, it is also possible to join the short sides of two blocks by interlocking them with the long side of one block. It can bring out the strangeness of the arrangement pattern. Grooves formed by chamfers on the upper edges of the outer peripheries of adjacent block surface plates are formed continuously in the vertical and horizontal directions to receive and drain rainwater, or allow the received rainwater to seep into the ground from the joints of the adjacent side walls. can. In addition, the short side and long side side walls of the block of the present invention are provided with vertical grooves whose upper ends are continuous with the chamfered portions, so that the blocks enter the grooves formed by the chamfered portions. Rainwater and other rainwater quickly flows down to the ground through the vertical grooves.
